Risk factors
By Mayo Clinic staffThoracic aortic aneurysm risk factors include:
- Age. Thoracic aortic aneurysms occur most often in people age 60 and older.
- Tobacco use. Tobacco use is a strong risk factor for the development of an aortic aneurysm. The longer you've smoked or chewed tobacco, the greater your risk.
- High blood pressure. Increased blood pressure damages the blood vessels in the body, raising your chances of developing an aneurysm.
- Buildup of plaques in your arteries (atherosclerosis). Atherosclerosis, the buildup of fat and other substances that can damage the lining of a blood vessel, increases your risk of an aneurysm.
- Being male. Men develop aortic aneurysms more often than women do. However, women with aortic aneurysms have a higher risk of rupture than do men.
- Race. Aortic aneurysms occur more commonly in whites than in people of other races.
- Family history. People who have a family history of aortic aneurysm are at increased risk of having one. People who have a family history of aneurysms tend to develop aneurysms at a younger age and are at higher risk of rupture.
